 The VModem script has been preconfigured to use **ttyUSB0** ​ as the default serial port name. Typically Raspbian will call its first serial port adapter **ttyUSB0** when using USB to Serial converters, and you won't need to modify this script. However, if the name is something **different**,​ such as **ttyAMA0**,​ you may need to update the script to point to the correct serial port name. The following section described how to double-check your serial port name: The VModem script has been preconfigured to use **ttyUSB0** ​ as the default serial port name.

Open up the script vmodem.sh for editing to make sure the baud and serial port are properly set. If you're unable to figure it out, feel free to contact me (see bottom of page).

 +  * Some computers are not capable of operating at fast serial speeds. If you're unable ​to connect at 57600 or faster, try slower speeds, such as 9600 baud at first. Adjust both the vmodem.sh script and the computer to connect at only 9600 baud. If that works, work your way up to see where the limit for your specific computer is.
